Sony PS-X700
(1981)

The last Biotracer biggie.

Alas a transitional unit and rather difficult to find nowadays, the PS-X700 was an updated PS-X75, using the redesigned (smaller) Biotracer tonearm and adding a neat tracking force LED display on the front strip - not that you'd use the latter feature every day but at least it was one more visible feature of technology :)

Unlike all other Biotracer-equipped turntables but its X75 elder, the X700 can have its VTA adjusted through a lever at the bottom of the arm base.
The other features are inherited from the previous generations of Sony's "X" turntables : Magnedisc/Xtal Lock, SBMC base, gel-filled height-adjustable feet and Linear Torque brushless/slotless BSL motor.

The PS-X700 seems to not have been available on every market, which makes it even more difficult to find.
